FAQ:Problem : My GPU isn't seen with my M.2 adapter?!?Answer : Some/Many M.2 to PCIe adapters do not properly ground pin #75, and have a higher resistance. Because of this, the motherboard doesn't recognize that an M.2 card/adapter has been installed and will not initialize the port.To resolve this, the user must either find a board that properly grounds pin #75, or solder a small jumper wire from pin #73 to pin #75. This is also not supported (by MSI, nor the moderation team), but it is a resolution to the issue. It should also be noted that it is generally understood that boards that do not properly ground pin 75 are of poor quality and stability could be a big problem using said boards.
